Say WHAT?!?!
Now I thought *I* used a lot of towels... holy moly dude. How in the world do you even find a place to USE 50 towels when detailing a car?
Lemee put it this way...
I'll use more towels when doing a paint correction than any other time. During that process I'll used a dozen or more to wipe compound. Add to that whatever I use to do a few alcohol/Eraser (home made Eraser) wipes to check progress on different panels, although that's likely no more than 3~4 more.
Then during the polishing stage I'll use about 8~10 more, and again whatever I need to do the Eraser wipes. (More of these if doing a coating, as it has to be surgically clean.)
That of course means if you are using a coating pre-cleaner you'll use maybe 6~8~10 more.
For the coating itself it really doesn't take but 6-ish tops.
So if there were 12, then 4, then 10, then 8, then finally 6 for the coating wipe you'll have 40 tops. Doing that is a multi-day process though, sometimes taking from 3 to 5 days!
Actually... if it's a sealant job you don't need to do all the Eraser steps, and about half the amount of LSP towels with a sealant as with a coating. It wouldn't be hard to cut the above number in half if doing a buff and seal. Then if it was an AIO you could get away with a dozen or so and call it a day.
Even at only 12~20 towels however that's plenty enough to make a wash load.:dblthumb2:
I have no problems with a compound towel sitting there for 3~4 days till I 'dirty' the rest. The ones I don't like to sit are sealant and coating towels. If I'm doing a spray wax/sealant (
and don't plan on washing them right away)... I'll wet the towels down with a diluted APC solution then spray them with straight hot water in the mud sink and rinse them, then hang them to dry.
This of course is talking about "paint quality" towels.
General duty and interior towels are a totally different situation. Those can be washed and taken care of in a different manner overall than your 'paint' towels. (
As in NOT with the paint towels.)
I do agree however that the OP needs to use more towels.
FWIW... I have a 'few' towels.

The gold 360's at the top are but just a few of those, there was 120 sitting around somewhere. Plus... There was a bin of dirty ones not in the photo, another load in the washer, and a good three~four dozen in my car.
This shot is pretty old... have added a few since then.
